Figure 1 is a side elevation of the lamp. Fig. 2 is a vertical section. j

The nature of my invention consists in obstructing the passage ofliquids' by means o1 an ai1' tight stop cock 01 other apparatus substantially the sa1ne, attached between the floor 'of'the fountain 01'- reservoir am]. the burners, thereby preventing the liquid from flowing into and finding its level in the burner; the obstructing cool: 0r apparatus being so constructed as t0 enable the operator to graduate the stream or quantity of liquid admittedfrom thence t0 .the burner in just such quantities as the construetion or dimensions of the burner 01' the nature of tl1e liquid t0 be burned may require. v

T0 enable others skilled in the art to make und use 1ny invention, I will proceed to describe its construction and Operation.v

I construct my lamp by using an ordinary fountain or reservoir A, with an open ing or openings (G) near to the base of' alle flow tube B, ma-de in the usual manner, through Which openings (Q) the liquid is ca1ised t0 fiow into a socket C, of the usual form, t0 which is attached a tube o1 tubes D, in the usual forma and in the usual manner, through which the liquid is conduoted to the burner F, but by means of an air tight stop cock E, 015 other apparatus substan tially the same, I obstructthe passage of the liquid before it is allowed to enter the burner F, whioh apparatus is connect-ed to and with the tube D, and by turning the coc z E, the flowi'ng liquid is admit-ted from thence to the burner- F, through a small aperture or apertures (a) made thnough the key H, of the cockE, suffieient only to admit such quantities of liquid as the dimensions of the burner mziy require for combustion, the stream 01' quantity of liquid so admitted through said cock E, may be graduated by turning the key H, of seid .its level with the perforated flow tubejB,

cool: 01' apparatus E, so as. to act asaperfect regulator to the flarne. The top or STATES PATENTOFFIGE,

burning -point of the burner F is ranged in J a horizontal line or nearly so'with the perforated fio w tube B, attached to the base of tl1e ord1nary fountain or reservoir A, in

the us ual manner, therby causingth'e liquid tofind its level at the top of the burner F,-- but flowing only in such quantities as the caiaacity of the burneror the natura 'of the liquid to be burned may v require. The burners may be made of brass, copper, iron, steel 01 any other metal and of such f01m 01 sliape as :fancy may dictate orutilit,7f

may require from time to time, such rad1al'd1sh shaped 01' concave ar'nis, con-Q 70,;

The liquid being ersj in manner aforesaid Will be consumed as its flows 01 feeds t0 theupper surface thereof, in its natural liquid state witliout'the introductad to the b1irn-= i fl aidof a wick 01' any. other capillary agent (a wich majr also be used if deSired) said liquid havinq (as before described) found 1 and being inflammable', Will be co1isumdas it feeds, ernitting a form or shape of flame corresponding With the form or construction of the burners 01 the nature o1 limpidity of-the fluid employ'ed to be burned and forming a perfect combustioh of all 01' any inflammalole liquicls, whether it be sperm' oil, camphene, spirits of turpentine, camphm rated spirit gas 01' any other liquid capable 015 producing a flame er of affording artificial light, which I have calleid the self operating lamp. Y

What I claim as my invention anddesire t0 secure y Letters Patent is The mode of regulating the fi0w of the oil er other inflammable liquid to be 0011-- manner above set forth 01' in any other modesubstantizilly the Same for afiording arti- JOSEPH PERRY, Enwn. A. Pownmn.-
